As with all other electronic utility tools, it's important to be aware of how to use and secure the phone. In the same way as using cards, it is not advisable to enter the PIN code openly. Also, select a PIN that is hard for others to guess and easy for you to remember. Never write down your PIN, but learn it by heart.
